Question

Why fluorine shows more resonance effect than chlorine?

Answer 1

Well flourine and chlorine are some of interesting elements.........they have very high electronegativety but also have alot lone pairs which they can give.........so they do create inductive effect and mesomeric effect(more dominant).....

Answer 2

heya0....

NO

Chlorine and fluorine do have a resonance effect, but it is much less in comparison to the instructive effect exerted by them.

Because of exceptionally high electronegativity of halogens, the magnitude of -I effect exerted by them is way more than the +R effect because of lone pair of electrons on them.

Hence, halogens (fluorine, chlorine, etc) are electron withdrawing groups.
